rAssnL-MAKING- ART Application fiIedNovember The invention relates, to:v the art of making .tassels for terminating cord units," such as used forornamental calendar cord hangers; fastener cords forpamphletsor booklets, as

'5 for example, souvenirs, programs, menus and dance orders; .bath rObe belts; curtain tiebacks; tie-cord for packages and other like P p s y Among theobjects of the invention there 10 is provided a novel method of applying tasselsf on a cord and an improved jmachine whereby said method. maybe easily carried out to .form anew article of manufacture,

said, machine comprising few and simple 15 parts which shall operate in proper sequence performing a continuous process whereby tassels-are secured along a cord and which shall be eflicient'and practical to a'high de gree'. The term cord as used herein is inribbon and other like materials. p In producing tassels embodying the invention, the units "of desired lengths are made in a continuous row onlan elongated'cord; so that they may be readlly handled for dyelng and as an article of manufacture for applying tosother objects, or for other purposes before being severed and finished. Thus the improvedprocess differs essentially fromthe well understood I hand manipulation methods of forming tassel units in'which separate cord units are severed prior to .individuaily forming the knotted tassels on the ends there- 0t Other objects of this invention will inpart be obvious and in part hereinafter pointed.

The invention accordingly consists in the features of construction, combinations of elements and arrangement of partswhich will 0 be exemplified in the construction hereinafter described and of which the scope of application: will be indicated inthe following claims. 1

,In the accompanying drawing, in which is shown various possible illustrative embodimentsof this invention:

Referringin detail to the drawing, 10 denotes an improved machinefembodying the invention and used in carrying outthe novel method formaking tasseis T firmlyknotted "in a'suita-ble manner, as at K and K along a cord C. The cord C maybe of any well ive views, correpectively, of

known strand construction, or may comprise I a suit-ablebraid or ribbon. As here shown the cord comprises tightly twisted strands, each covered Witha cotton or natural or artificial silk layer of any desired color or colors. The tassels T maybe formed of loosethreads of" mercerized cotton, natural or artificial silk or other fibrous material bunched or bundled together and fiiredlyattached at spaced disg tance along the cord C the. knots I 1 and K Said knots comprise any suitable type of tie fastening construction, as for example,

the cord C. As here shown the machine 10 is seen to comprise mechanism I for supplying a continuous strand S for the bunches of tassel threads, mechanism II for severing the strand S into uniform lengths and feeding same in proper sequence in the tassel tying operating, mechanism III for'retaining a'portion of the cord C and forming a loop L in said portion of the strand, mechanism IV for entwining the severed bunches of threads of the strand S with the loop L of the cord and tightly tying same to form the knotted tassel T, and mechanism V for feeding the cord C through the machine in cooperative timed relations with the movements of the mecha-' nisms I, II, III and IV.

In carrying out the improved process and providing the machine 10 embodying the invention it is contemplated through mechanism I to supply either spooled threads (not shown), in the well understood manner, to form the continuous strand S of threads fed to the machine to form the tassels T or to use threads just as they come commercially in example, as used in cotton and woolen textile mills forspinning yarns.

The mechanisms II, III, IV and V are carried on a frame ll and are actuated by a suitable power transmission P through a main drive shaft 12 journalled in aligned bearing blocks 13 which are supported in spaced rela tion on the frame 11.

Mounted to turn. with the shaft 12 are cams 14, 15, 16- and 17 of any suitable well understood construction. Said cams engage with ends 18, 19 20 and 21, respectively, of the rods, l8, 19, 20 and 21, respectively. The other ends 18" and 19", of the rods 18 and 19, respectively, are suitably pivot-ed to'arms 22 and 23 respectively, of bell cranks 22 and 23, respectively.

= The mechanism II includes thebell crank 22 mounted for rocking movement on a bearmg 26 CitIIlECl by the. frame and has an arm 22"-suitably connected, as at 27, with one end 28 of a slide shaft 28 for reciprocating the latter through a sleeve bearing 29 supported ates with another knife blade 33 forsevering aportion of the strand S of the bunched loose threads from which the tassels T are made. The fingers 3O serve to fold the severed portion of the strand S about the cord C inthe knot tying operation as will hereinafter he more fully described.

The severed strand feeding portion of mechanism II may comprise gripper members 34 which are reciprocatingly carried on a rod 35, the latter being pivotally connected, as at 36, to the swinging end 37 of a lever 37. 'The lever 37 is pivotally anchored as at 38 on the frame 11 and connects with one end, 39 'of a: slide rod 39. The other end 39* of saidrod engages with a cam 40 driven from the main shaft 12 for actuating the gripping member 34 through the rod 39, lever 37 and rod 35, as is clearly shown in Fig. 3.

The mechanism III includes the bell crank 23 mounted for rocking movement, as on hearing 44 supported by the frame 11. Said member'23 has an arm 23 connected in any suitable manner, as shown at 4-5, with one end 46* of a sliding shaft 46 which extends through a bearing 47 carried by the frame 11. The other shaft end 46 terminates in a forked hook member 46, the latter being adapted to engage with the cord C to form the closed or twist loop L therein. In making the twist loop L for knotting the tassel T, the shaft 46 and hook member 416 is not only reciprocated but must also be rotated substantially through three-quarters of a turn or more. To thisv end theshaft 46 may have a suitably splined connection with a pinion lfil mounted to turn therewith, Said pinion 4C8 meshes with a gear sector .49 which is swingably connected with one end 20 of the cam rod 20.

The mechanism IV includes the cam 17 which engages one cam rod end 21 the other end 21 of the rod 21 is suitably connected, as at 50, for swinging a lever 51 about its end 51 pivoted on the frame 11. The free end 51 of said lever is suitably connected as at 52 with one end 53 of a rod 53, the latter being mounted for reciprocating movement through a bearing 54 extending from the frame 11. The other end of the rod 53 terminates in a gripper member 55 having a head 55 a collar 55 mounted to slide on the rod 53 and to cooperate with the head toform gripping jaws for drawing the strand end portions E through the twist loop L of the cord and tightening the knot K in the manner as will hereinafter appear. 7

The gripper member 55 also includes a coil spring 56, a crank lever 57 and a buffer stop 58. The spring 56 is carried on the :rod 53 between the collar 55 and the bearing 54 and is normally in compression for urging the collar jaw 55 against the head jaw 55. The bell crank lever 57 may be pivoted to the frame 11 as at 57 a and has one arm terminated by alatch 57- for engagmg a flange 55 'Ill) 'tion.

Saiddouble gripper is seen to comprise spaced fixed jaws 61? between which the forlied'hook member 46 1noves'- for engaging. with the portions o'f-"the cord C extending over said ja-Ws' in' the path of travel of said member; Each jaw 61", hasacooperating movable jaw 6P Whichclamps the cord Q between them during the knot tying 'opera The jaws 61?" are moved in ancient of ble linkage such-as rod 63; and a bell crank 64 interconnecting said rodvwith a linlr'65 en; gaging with, the cam 17' for actuating said gripper-jaws 61 as is clear froi'nFigfli The mechanism V comprises afwinding de vice 66 which may be ofa ny well understood construction for intermittently feedingthe cord C through the maChineQlO, as ,for ample, including a rolle'r'67 driven by asuie able sector gear '68'and'pinion 69fr'om the rod 2l'through a clutch 7O-and a-pressure'roller 7-1 Coactixig--with the roller 67. The cord gripped between the rollers67 andfi71 isfed with the rotation of the roller 67 through the intermittent reciprocation movement of the rod 21'of the mechanism IV.

tiv'elyopposite 'directionsa'Fig-J 9 showsth 93c i I formation of the tassels with knots K and K Of course machine 10 maybe readily .designed to alternately form tassels with knots K and K but preferably two machines 10 are operated in series as shown diagrammatically in Fig. 1 so that each machinemakes one type of knotted tassel on the same cord, thus the production is speeded up and both types of tassels with knots K and K are simultaneously produced. After the tassels T have been firmly knotted to the cord C. the latter is cut at X and Y between the adjacent knots K and K thereby forming cord units having the tassels T extending outwardly from the ends thereof.

Figs. 6 and 6 show another type of knotted tassel structure T for tying the tassels to the cord. This differs from theknotted structure described above and shown in Figs. 5

and 5, in that the cut endgX of the cord 0 extends down into the loop L instead of passing outwardly away from the loop L of the knots K or K of tassels T.

Still another type of knotted tassel structure T tied to the cord is shown'in Figs. 7 and 7 Here no closed or twisted loop is formedbut insteadthe cord Cis simply folded with a big-ht, as at F, said fold engaging with the fold bight B of the severed bunch strand in the same manner as in forming an ordinary square knot; After such a I knotted tassel T has. been tightened the bights F and B of the folds firmly retain the tassel knotted structure against disengagement.

For some purposes it is desirable to provide tassel cord units with double. loops as for example, as shown in Fig. 8. Here the cord C has loops D formed therein, each loop having a tasselT" terminating the ends thereof. These tassels T may be tiedin any suitable way as by means of a square knot. After the double loops D and tassels T are made on the cord C, the units are separated and completed by severing-the cord at X 7 i It will thus be seen that-there is provided a method, a device for carrying out said meth- 0d, and article of manufacture in which the severalobjects of this invention are achieved and which is well adapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention, andas various changes might be made in the embodiment aboveset fortln'itis to be understood that all matter herein set forth or shown in the accompanying drawing is to-be interpreted as illustrative and not in a limiting sense.
